Colonial Revival is the most widely built style in American history, running from the 1880s through today and accounting for the millwork in millions of homes — from 1920s Cape Cods to modern center-hall colonials. The style consolidates Georgian, Federal, and Greek Revival elements into a more accessible vocabulary: clean crown profiles, fluted casings with corner blocks or mitered returns, six-panel doors, and chair rails sized for everyday rooms. Mason’s Mill carries 43 Colonial Revival profiles that match the standard millwork found in pre-war and post-war traditional homes. This is the right category for most “we want it to look colonial” renovations and additions where strict period accuracy isn’t required.
Thermac Poplar is a thermally modified Appalachian hardwood produced by Bingaman & Son Lumber from native Pennsylvania yellow poplar. Using only heat and steam — no chemicals, plastics, or additives — the wood is heated in a low-oxygen environment to fundamentally alter its cell structure. This process removes the sugars and moisture that fungi and insects need to survive, while permanently reducing the wood's ability to absorb water. The result is a stable, rot-resistant hardwood with a warm, chocolate-brown color that runs consistently through the entire board, not just the surface.
Yellow poplar is particularly well-suited to thermal modification: it's a domestically abundant, fast-growing hardwood that emerges from the process with excellent dimensional stability, a smooth grain, and a rich color that rivals more exotic species. Independent testing on thermally modified yellow poplar has demonstrated Durability Class 1 ("very durable") performance against wood-destroying fungi, placing it in the same durability tier as many tropical hardwoods.
Each board is finished with Cutek Extreme Clear, a penetrating oil that migrates deep into the wood fibers rather than forming a surface film. Cutek's core function is dimensional stabilization — it works from inside the board to slow moisture movement, which is what causes cupping, checking, and end-splitting in exterior wood. Because the finish penetrates rather than coats, it cannot peel or flake, and maintenance requires no sanding or stripping — just clean the surface and re-apply when it looks dry. The clear formulation adds no pigment, so the poplar's natural thermally-modified brown will show through initially and gradually transition to a silver-gray patina if left unmaintained with a colortone.
Ideal for exterior siding, soffits, porch ceilings, cladding, and covered outdoor applications where a domestic hardwood with contemporary durability is desired.
